ESP8266 Community Forum

My thanks for publishing such a nice book on ESP8266. I have downloaded free copy but I will purchase it along with your other book on Raspberry pi. I have few questions
1. what is range of ESP-01 , ESP-07 , ESP-12 module indoor & outdoor (in meters)
2. How much RAM does ESP8266 module have - I want to hold TCP data from TCP client in RAM & send it to UART when TCP client application has sens complete data according to application requirement .

Thanks for this book. I love free books and I appreciate the business model. When and if I complete the book I might donate some additional money.
